这是一项相当艰巨的任务:-)
它由您正在使用的完成程序处理。完成者的complete()
方法只能用于搜索最后一个空白后的内容。
如果你在图书馆的FileNameCompleter
寻找例如:未进行此操作可言,所以你会发现没有完成,因为<input1> <input2>
完成者搜索,不仅为<input2>
:-)
你会必须自己实现一个能够找到input2的完成者。
此外,CompletionHandler
必须将您发现的内容附加到您已输入的内容上。
这是一个基本的实现更改默认FileNameCompleter
:
protected int matchFiles(final String buffer, final String translated, final File[] files,
final List<CharSequence> candidates) {
// THIS IS NEW
String[] allWords = translated.split(" ");
String lastWord = allWords[allWords.length - 1];
// the lastWord is used when searching the files now
// ---
if (files == null) {
return -1;
}
int matches = 0;
// first pass: just count the matches
for (File file : files) {
if (file.getAbsolutePath().startsWith(lastWord)) {
matches++;
}
}
for (File file : files) {
if (file.getAbsolutePath().startsWith(lastWord)) {
CharSequence name = file.getName() + (matches == 1 && file.isDirectory() ? this.separator() : " ");
candidates.add(this.render(file, name).toString());
}
}
final int index = buffer.lastIndexOf(this.separator());
return index + this.separator().length();
}
而这里CompletionHandler
的complete()
- 方法更改默认CandidateListCompletionHandler
:
@Override
public boolean complete(final ConsoleReader reader, final List<CharSequence> candidates, final int pos)
throws IOException {
CursorBuffer buf = reader.getCursorBuffer();
// THIS IS NEW
String[] allWords = buf.toString().split(" ");
String firstWords = "";
if (allWords.length > 1) {
for (int i = 0; i < allWords.length - 1; i++) {
firstWords += allWords[i] + " ";
}
}
//-----
// if there is only one completion, then fill in the buffer
if (candidates.size() == 1) {
String value = Ansi.stripAnsi(candidates.get(0).toString());
if (buf.cursor == buf.buffer.length() && this.printSpaceAfterFullCompletion && !value.endsWith(" ")) {
value += " ";
}
// fail if the only candidate is the same as the current buffer
if (value.equals(buf.toString())) {
return false;
}
CandidateListCompletionHandler.setBuffer(reader, firstWords + " " + value, pos);
return true;
} else if (candidates.size() > 1) {
String value = this.getUnambiguousCompletions(candidates);
CandidateListCompletionHandler.setBuffer(reader, value, pos);
}
CandidateListCompletionHandler.printCandidates(reader, candidates);
// redraw the current console buffer
reader.drawLine();
return true;
}
嗯,。所以这需要比我想象的更大的改变。感谢您的洞察! – flakes
至少它似乎无法通过某些配置激活它。但是你可以制定一个标准的实现并为你的下一个类继承它。 –
